Ultrasonic Lithium Battery Spraying Equipment: Precision Empowerment Rau Siab -Quality Upgrade Of Lithium Battery Industry

Lub luag haujlwm tseem ceeb ntawm ultrasonic lithium roj teeb txau cov cuab yeej yog siv piezoelectric ceramic transducers los hloov hluav taws xob hluav taws xob rau hauv siab - zaus tshuab vibrations ntawm 20kHz-120kHz. Los ntawm capillary yoj fragmentation, lub lithium roj teeb slurry (zoo electrode, tsis zoo electrode, electrolyte, los yog ceramic slurry, thiab lwm yam) yog atomized rau hauv uniform micro-droplets ntawm 1-50μm. Cov tee no mam li maj mam thauj mus rau qhov chaw substrate ntawm qhov qis qis (<1m/s) by a low-pressure carrier gas. After drying and curing, a dense and uniform functional coating is formed. The entire process requires no high-pressure airflow assistance, fundamentally solving the pain points of traditional processes.

Tsis zoo li cov tsoos siab -pressure airflow spraying thiab hniav txheej txheej txheem, ultrasonic spraying tag nrho rau siab - zaus vibration zog rau atomization, tshem tawm qhov xav tau rau siab - siab cuam tshuam. Qhov no tiv thaiv txheej txheej tsis xws luag tshwm sim los ntawm cov dej agglomeration thiab splashing, thiab ua kom tsis muaj - sib tiv tauj txheej, tiv thaiv tsis yooj yim substrates xws li ultra- cov khoom tam sim no nyias (cov ntawv nyiaj tooj liab thiab cov ntawv txhuas hauv qab 6μm) thiab hloov tau yooj yim cais tawm ntawm kev puas tsuaj. Lub caij no, los ntawm kev tswj tsis tau meej xws li ultrasonic amplitude, txau nrawm, lub taub hau deb, thiab slurry txaus tus nqi, txheej txheej tuaj yeem tswj tau ntawm nanometer mus rau micrometer qib, nrog lub thickness uniformity yuam kev tsawg dua los yog sib npaug rau ± 2% thiab porosity uniformity yuam kev txo rau ± 1%.

Core zoo:

Superior Coating Quality, Laying a Solid Foundation for Battery Performance A uniform and dense coating is a core prerequisite for improving the performance of lithium batteries.

Ultrasonic txau atomizes slurry rau hauv cov micron zoo li - cov me me, ua rau cov txheej tsis muaj pinholes, agglomeration, thiab ntug teebmeem. Qhov no ua tau zoo kom tsis txhob muaj teeb meem xws li txheej txheej tsis sib xws, tawg, thiab cov txheej txheem tsis pom nyob hauv cov txheej txheem ib txwm muaj, txhim kho qhov sib xws ntawm electrodes thiab cov khoom sib cais. Piv txwv li, nyob rau hauv cov txheej txheem electrode, txheej txheej txheej tuaj yeem ua kom luv lithium - ion txoj kev tsiv teb tsaws, txo lub sijhawm them roj teeb ntau dua 30% piv rau cov txheej txheem ib txwm muaj. Nyob rau hauv cov txheej txheem sib cais, cov txheej txheem tswj hwm cov txheej txheem ceramic tuaj yeem txhim kho qhov sib cais cov cua sov kom dhau 200 degree, ua kom muaj zog tiv thaiv siab - kub thermal shrinkage thiab txo qhov kev pheej hmoo ntawm cov roj teeb luv luv. Ib txhij, gradient txheej tsim tuaj yeem ua tiav los ntawm kev hloov pauv, xws li manganese - nplua nuj txheej txheej thiab npib tsib xee- nplua nuj txheej hauv qab, ua kom zoo dua roj teeb hluav taws xob ua haujlwm thiab pab txhawb kev txhim kho siab - zog- roj teeb ntom ntom.

(II) Kev siv cov khoom siv siab, ua tiav qhov yeej - yeej qhov xwm txheej ntawm kev txo nqi thiab kev txhim kho kev ua tau zoo

Lithium-ion roj teeb slurries feem ntau muaj cov hlau zoo xws li cobalt, npib tsib xee, thiab platinum, nrog rau cov khoom muaj txiaj ntsig zoo xws li graphene thiab carbon nanotubes. Cov khoom poob ncaj qha cuam tshuam cov nqi tsim khoom. Cov txheej txheem tshuaj tsuag ib txwm raug kev txom nyem los ntawm qhov tsis sib xws ntawm atomization thiab loj splattering, uas ua rau slurry poob ntau tshaj 15%. Ultrasonic spraying, nrog nws cov meej atomization thiab directional deposition muaj peev xwm, tuaj yeem nce kev siv cov khoom mus rau 85% -95%, txo cov khoom pov tseg ntawm cov khoom muaj nqis. Qhov no yog qhov tshwj xeeb tshaj yog tsim rau txheej txheej siab - cov txiaj ntsig catalyst kev daws teeb meem, txo qis cov nqi tsim khoom lag luam. Hauv kev tsim khoom loj loj, qhov txiaj ntsig no tuaj yeem txhais ua cov txiaj ntsig tseem ceeb ntawm kev lag luam, pab cov tuam txhab tsim cov nqi kom zoo dua hauv kev sib tw ua lag luam hnyav.

(III) Cov txheej txheem muaj zog sib raug zoo, ua kom haum rau ntau hom kev xav tau

Ultrasonic lithium-ion roj teeb txau cov cuab yeej muaj cov txheej txheem siab heev, sib xws nrog ntau lub tshuab slurry xws li dej-raws li thiab hnyav-raws li slurries, thiab yoog raws li cov kev xav tau txheej txheej ntawm tag nrho cov khoom tseem ceeb ntawm lithium{3}} ion roj teeb, suav nrog cov khoom siv hluav taws xob zoo, cov hluav taws xob tsis zoo thiab cov khoom sib cais. Txawm hais tias nws yog cov txheej txheem slurry ntawm high-nickel cathodes thiab silicon-carbon anodes, ceramic txheej thiab polymer txheej hloov pauv ntawm cov khoom sib cais, lossis cov tshuaj tiv thaiv -corrosion txheej ntawm tabs thiab cov txheej txheem tiv thaiv ntawm cov plhaub, cov cuab yeej tuaj yeem ua tiav txheej txheej los ntawm kev hloov pauv. Tib lub sijhawm, cov cuab yeej hloov pauv mus rau ntau qhov xwm txheej xws li kev sim R&D, kev tsim cov tsav tsheb, thiab kev tsim khoom loj, suav nrog ntau yam qauv xws li desktop, pilot-scale, thiab conveyor hom, ua tiav cov txheej txheem tag nrho los ntawm kev txheeb xyuas cov qauv mus rau loj - teev ntau lawm.

(IV) Ntsuab, ib puag ncig tus phooj ywg, thiab muaj txiaj ntsig zoo, sib txuam nrog kev lag luam kev loj hlob

Piv nrog rau cov tsoos siab- siab txau uas yuav tsum muaj ntau qhov siab - cua siab, ultrasonic spraying tsis xav tau siab -pressure airflow kev pab, txo cov kuab tshuaj evaporation los ntawm 30% -50% thiab txo VOC emissions, ua raws li qis - roj teeb kev lag luam kev lag luam. Tsis tas li ntawd, cov khoom siv tau txais kev tsim qauv tsis yog- clogging, thiab atomization tsis cia siab rau qhov me me - txoj kab uas hla nozzles, ua kom tsis txhob muaj kev tu ncua sij hawm los ntawm slurry clogging, txo cov sij hawm cuam tshuam ntau lawm, thiab txhim kho kev tsim khoom; ua ke nrog cov khoom siv hnyav rov qab, cov nqi ib puag ncig tuaj yeem txo qis ntxiv, ua tiav cov txheej txheem kaw-loop ntsuab.
